Javascript Regex to ignore first character in match

I need to ignore a '.' at the start of my regular expression, and have been somewhat stumped.

My current regex is: 

(?::)(\d{3})

Which matches the following:

When I try to ignore the '.' with the following regex:

[^.](?::)(\d{3})

I get this:

As it seems to be adding the extra character like '<', which is unwanted.

How do I go about to ignore that extra character in front of the ':' ?

Just use a lookahead to match the strings in this :\d{3} format preceded by any but not of dot.

(?=[^.](:(\d{3})))

DEMO

Group 1 contains the string with :, and the group 2 contains only the digits.

Use this alternation based regex:

\.:\d{3}|:(\d{3})

And grab captured group #1 for your matches.
